[0002] The discharge unit in an existing ozone generator usually includes a pair of discharge unit mounting plates, several outer electrodes installed in a concentric circle structure, a dielectric tube and an inner electrode. The mounting plates, outer electrodes and inner electrodes are generally made of metal, and the outer electrodes are fixed and sealed to the fixing plate by welding.

[0003] Since the welds may be uneven and may contain protrusions or burrs, the discharge during operation of the ozone generator may cause vibrations, which may cause the dielectric tube to collide with the welds. This may damage the dielectric tube, causing it to break and leak, which in turn may damage the discharge unit or even the ozone generator. In addition, since the outer electrode opening may also be uneven, the discharge during operation of the ozone generator may cause vibrations, which may cause collisions between the dielectric tube and the outer electrode opening. This may also damage the dielectric tube, causing it to break and leak, which in turn may damage the discharge unit or even the ozone generator.

[0004] Therefore, an ozone generator with a simple structure and not easy to damage is needed to meet practical needs. Summary of the Invention

[0010] 3 The inner electrode is a high voltage electrode, and the first end of the inner electrode is connected to the positive electrode of the power supply.

[0011] The inner electrode is a high-voltage electrode, and one end or both ends of the inner electrode are simultaneously connected to the positive electrode of the power supply.

[0012] 5 The distance between the end of the outer electrode extending toward the gas chamber and the discharge unit fixing plate where it is located shall not exceed 10 mm.

[0013] 6. The distance between the end of the outer electrode and the discharge unit fixing plate where it is located is between 2 and 8 mm.

[0014] The inner electrode, dielectric tube and outer electrode are concentric circles, and a discharge air gap exists between the inner electrode and the dielectric tube, or between the dielectric tube and the outer electrode, or between the inner electrode and the dielectric tube and between the dielectric tube and the outer electrode.

[0016] 9. The outer electrode is welded and sealed to the discharge unit fixing plate.

[0017] The ozone generator using the technical solution of this utility model has the following advantages:

[0018] 1. The welding point between the outer electrode and the fixed plate is at a distance from the end of the outer electrode to prevent the discharge between the inner electrode and the outer electrode from damaging the weld and causing water leakage between the outer electrode and the fixed plate; effectively reducing the equipment failure rate, extending the equipment service life, and saving maintenance costs.

[0019] 2. The welding point between the outer electrode and the fixed plate is at a distance from the end of the outer electrode to avoid damage to the dielectric tube caused by the uneven welding point, which may lead to damage to the dielectric tube and even damage to the discharge unit and even the ozone generator; thus reducing equipment failure rate and saving maintenance costs.

[0020] 3. The end of the outer electrode is in the shape of a bell mouth, and the inner side of the narrow mouth of the bell mouth is round and smooth. When the ozone generator discharges and generates vibrations, it protects the dielectric tube from being damaged by the outer electrode port, thereby extending the life of the dielectric tube, reducing the equipment failure rate, and saving maintenance costs.
